[MapServer-users] Shapefile of Points

[Jörg Thomsen (WhereGroup)]

Hi,

here are a lot of examples for symbol-definitions and using them in the 
mapfile: https://mapserver.org/mapfile/symbology/construction.html

> I intend to create 32 point symbols by varying the color, 

you'll need only one symbol-definition. assign the color in the mapfiles 
style-section.


> I have a suspicion that I should use mapscript to assign the symbols to 
> each data range from php, for example, if the range is between 0-1.99, 
> strong red symbol, 2.00-3.99 light red symbol...

this is done bei the EXPRESSION within the class-section
see https://mapserver.org/mapfile/class.html


> I'm doing this in qgis, and each shapefile has a different set of data 
> in range, this makes me think that I should calculate the quantiles from 
> the shapefile data and then assign the color symbols using php and 
> mapscript to create the .map file

you can do the classification in qgis and use the extension 'GeoCat 
Bridge' to create the layer-sections of your mapfile.
